Answer:
Active transport
Explanation:
Active transport is defined as the movement of ions or molecules from a region of lower concentration into a region of higher concentration by the use of energy. Two examples of active transport include the uptake of glucose in human intestine and the absorption of mineral ions into plant roots.
Active transport requires energy because it involves the movement of molecules against an existing concentration gradient.
The conclusion that you can draw about the electron
transitions that can take place for a magnesium atom is that the photons produced
are not of a lone wavelength, therefore from many dissimilar levels to
subsequent levels, with many different wavelengths joining to create white.
Johnny should have thrown away the unused chemicals because they still could have mixed with the other chemicals and it could cause a reaction.
